STEVEN GERRARD reckons the losses of Ryan Jack and Scott Arfield have proven the strength and depth of his Rangers midfield ranks this term.

Jack hasn't featured for the Light Blues since the win over Aberdeen at Ibrox, while Arfield has been ruled out for the foreseeable future after picking up an ankle injury against Hibernian.

Steven Davis and Glen Kamara are set to start the Old Firm showdown with Celtic on Saturday and Gerrard can still call on the likes of Joe Aribo and Bongani Zungu to bolster his central three.

Gerrard said: “I made it quite clear that it was important we got someone in the door before the window shut.

“Getting Bongani up to speed was the priority because over the course of the season, with the schedule we have, we were always going to get a knock or two.

“Ryan Jack being out for the amount of time he has has been a real disappointment for me.

“Scott Arfield’s absence is a bit of bad luck from a challenge he had against Hibs. So it does make us slightly light in that area.

“But having Bongani there is a big help. Joe Aribo getting back up to speed and back to form as quick as he has is a real positive.

“I thought both him and Glen Kamara were superb against St Mirren. Steven Davis, aside from one or two moments early on, again showed why he is so important to us as well."
